Invoice Generator
Make an invoice in the browser: parties, number, dates or Net terms, line items, discount, tax, shipping, amount paid — print or save as PDF, no sign-up.
A printable invoice whose lines add up to its total, the balance due after payments, the due date from your terms, a plain-text copy and a CSV of the lines — nothing sent anywhere.
Example: Design work 10 × 85, hosting 12 × 20, licence 300 at 0 % tax, 5 % discount and 10 % tax: subtotal 1 390, tax 103.55, total 1 424.05; 500 paid leaves 924.05 due 30 days after the invoice date.
Lines that add up,
printed by your browser.
How the totals are built, how the items and dates are read, and what the page does not do.
The arithmetic
Each line is quantity × unit price rounded to two decimals before anything is summed, so the printed lines always add up to the printed subtotal. The discount is a percentage of the subtotal; tax is charged on what remains, at the global rate or at the rate typed as a fourth value on the line (0 for an exempt item); shipping is added after tax; the amount paid comes off the total to give the balance due. Prices marked tax-inclusive are divided by (1 + rate) first and the tax shown separately.
Items, terms and dates
Items are one per line: description, quantity, unit price and an optional tax %, separated by commas, semicolons, tabs or bars — the numbers are read from the right, so a description may contain commas, and a comma between a digit and three digits (1,250.50) is a thousands separator. Dates are YYYY-MM-DD; with terms such as "Net 30" the due date is the invoice date plus 30 days, and "due on receipt" makes it the invoice date. A typed due date always wins.
Printing and limits
Print / save as PDF uses the browser's own print dialog: the form and cards are hidden and the document prints on A4 (choose "Save as PDF" as the printer). The text copy and the CSV of lines are for pasting into other systems. The page applies no tax law and knows no legal requirement — what an invoice must state (tax IDs, sequential numbering, wording) depends on where you are. Nothing leaves the browser; the same four anonymous usage counts as the rest of the site apply.
